How can I get divorced if I got married, did my husband's permanent residence card and now he has other family in Mexico?

If you are married no matter where you got married you can file for divorce in the County in which you are a resident for at least three months for a legal separation or six months for a divorce. Good luck.

You can file a divorce action in California if you have lived in the State for 6 months and the same county for 3 months. Depending where the husband lives could present challenges to serve him the Petition. It would be much easier if you serve him in California or he signs a document acknowledging service of the divorce Petition.
